Burgers' equation with a transonic rarefaction wave.
Comparison of results obtained with or without the entropy fix. This is set in the Riemann solver by modifying the variable efix and recompiling.
Note: also try changing mx to an odd value (e.g. 61 instead of 60). Then there is one grid cell with the value 0.5 at x=0 and a different weak solution is obtained.
